Abstract
Abstract A storage apparatus such as a copier or facsimile machine which stores information on paper and uses parts which the operator replaces upon expiration because of consumption of the part or deterioration of the part. A system is provided so that the consumable part can have its life-time measured by devices on the main body of the storage apparatus. Each consumable part has an indication of what stage of consumption or state within its life-time that it has reached. That is, for a copier after a certain number of copies are made one of a number of fuses in the consumable part can be fused as an indication of the state of the part.
